REFLECTOR. I

Specification of Letters Patent.

Application filed October 7, 1905' Serial No. 281,776.

To all whom it may concern:

Be it known that I, ZEELIG MA'rLowsKY, a citizen of the United States,and a resident of the city of- New York, borou h of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedReflector, of which the following is a full, clear, and exactdescription.

This invention relates to reflectors made of glassware or porcelain andused with lights or lamps; and the object of theinvention is to producean improved form for the surface of such parts as will benefit theirreflecting qualities.

The invention consists in the construction and combination of parts tobe described 2 is. a cross-section showing a portion of the.

- wall of a globe and illustrating clearly a form which its surface maytake; and Fig. 3 is a view similar to Fig. 2, but representing adifferent construction of the surface of the globe.

Referring more particularly to the parts, 1 represents a lamp-globe,which may have a su stantially sphericaL'body 2 and a reduced neck 3therebelow, as shown. It should be understood that in pra fee the sourceof illumination will be located substantially the center of the body 2;'In forming a globe according to my invention I provide its surface witha plurality of cavities 12 of substantially pyramidal form, the samepreferably being arran ed in horizontal and vertical rows, as in icated.I prefer to form these cavities 12 on the outer sidegof the lobe, sothat pyramidal projections 12 are fbrmed on the inner side, as indicatedin Fig. 2. These cavities are arranged in horizontal and vertical rows,presenting sharp edges 13 on the outer side between the cavities. Theinclined faces 14 of the cavities do not meet .however, is the same asbe ore.

below, butare connected by flat surfaces 10. On the inner face of theglobe recesses 16 are formed which are in alinem'ent with the edges 13,said recesses presenting inclined clined aces are reflected through thetrans- I lucent surfaces 10. In this way the light coming from theilluminated point is diffused, so that the entire globe appears to be alow.

In ractice the cavities 12 are so smaIl relative to the size of the lobethat the effect is pro need of myriads 0 illuminated points.

Instead of forming the cavities on the outer side of the globe, asindicated at 4 in Fig. 2,1 may form them on the inside, as indicated inFig. 3. The principle applying in this case,

Referring to this figure, the cavities 4 are formed with substantiallyflat bottoms 7. A reflecting-coating 8 is applied to the inclined sidefaces 5 of the cavities, but is not applied to the surface 7. With thisform the inclined faces 5 meet i in sharp edges 6 on the innerside-ofthe globe,

as shown.

While I have described the invention as applied to a globe and referthat the globe shall be constructed 0 glass, in ractice I may make thereflecting body 0 anyform desired. Thus I may form the surfaces onchimneys in the manner described above.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A reflector ada ted to surround an illuminatedpoint-an having upon its surface a plurality of cavities presentinginclined faces coated with a reflecting substance, said cavities havinguncoated bottoms through which the reflected light may pass.

2. A reflector having in its surface a plurality of cavitiesformed inrows and presenting substantially flat surfaces at their bottoms, withinclined side faces, said inclined 5 faces having a coat of a reflectingsubstance adapted to reflect light through said bottom faces.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
